As technologies have been developing, our lives are getting easier. Today we are surrounded by the new technologies such as AI and IoT. Moreover, the word, "smart" is a very broad one because we are trying to change our daily environment into smart one by using those technologies. For example, the traditional workplaces have changed into smart offices. Since the 3rd industrial revolution, we have used the touch interface to operate the machines. In the 4th industrial revolution, however, we are trying adding the speech recognition module to the machines to operate them by giving voice commands. Today many of the things are communicated with human by voice commands. Many of them are called AI things and they do tasks which users request and do tasks more than what users request. In the 4th industrial revolution, we use smartphones all the time every day from the morning to the night. For this reason, the privacy using phone is not guaranteed sometimes. For example, the caller's voice can be heard through the phone speaker when accepting a call. So, it is needed to protect privacy on smartphone and it should work automatically according to the user context. In this aspect, this paper proposes a method to adjust the voice volume for call to protect privacy on smartphone according to the user context.

The present asylums are reported to be hurting the privacy and self-reliance of the individuals by the uniformed manugerial regulations and fragmentary service. Due to the poor linkage of service and uneven quality between facilities, when a person falls into a serious disease he should bear the inconvenience of moving to other facility for the treatment. This study is to investigate the types and pater of welfare facilities for the aged where they can be provided with flexible service in the continuous living environments and to suggest the ideal environments for them to stand on their own feet by assisting properly both in physically and mentally keeping their privacy and sociality.

해양수산부는 지능형 해상교통정보 체계 운영을 통해 해사안전 서비스를 제공 중이며, 제공 중인 서비스의 경쟁력 확보를 위한 신뢰성 및 품질 향상 연구가 지속적으로 필요한 상황이다. 이러한 경쟁력 확보를 위해, 지능형 해상교통정보 체계의 실시간 운영 영향을 최소화하는 대용량 해양정보 연계 시스템에 대한 기본설계를 수행하고, 개인정보 보안 문제와 전체적인 시스템 실현을 위해 가명화/암호화 절차가 적용된 이론적 하드웨어 구조도를 제시한 바 있다. 하지만 제시한 구성도 및 설계는 전체적인 개념만을 포함하며, 실제 사용되고 있는 실시간 해양정보 연계를 위해서는 대한민국의 개인정보 보호법을 만족할 수 있는 상세한 개인정보 보안 방안이 요구된다. 이 연구는 이러한 문제의 해결을 위해 지능형 해상교통정보 연계 시스템에서 연계하는 실시간 해양정보 내에서 개인정보 보호법을 침해할 수 있는 요소(선주, 선사, 선장, 항해사, 어민 등의 개인정보)를 식별하고, 식별한 개인정보를 가명화/암호화하여 타 기관으로 연계할 수 있는 방법을 연구한다.

The objective of this research is not only making the planning guides regarding a small-scale residential remodeling but also examining closely the social roles of the interior design for the poor and the underprivileged class by analyzing the residential remodeling cases. The scope of research includes 40 remodeling houses free of charge which are broadcasted in the TV program 'Love House'. Taking in consideration the characteristics of users like parentless or single-parent families and families with disabled persons, this study uses the spatial approach, user's convenience approach and psychological problem solving approach, in terms of the methodology. In result of the analysis of their interior design, first of all, it is essential solving the problem of limited house space by comparison with the family number. Second, the universal design concept for the family with disabled persons(72.5%), old persons or children is strengthened guaranteeing privacy in small and old interior space. Third, the interior design is focused in increasing communication among family members, because mental and physical obstacle would obstruct accessibility among them. This research shows the importance of the interior design which makes wide social roles contributing to create "welfare society".

Information security reports four types of basic attacks on information. One of the attacks is named as fabrication. Even though mobile devices and applications are showing its maturity in terms of performance, security and ubiquity, location-based applications still faces challenges of quality of service, privacy, integrity, authentication among mobile devices and hence mobile users associated with the devices. There is always a continued fear as how location information of users or IoT appliances is used by third party LB Service providers. Even adversary or malicious attackers get hold of location information in transit or fraudulently hold this information. In this paper, location information fabrication scenarios are presented after knowing basic model of information attacks. Peer-to-Peer broadcast model of location privacy is proposed. This document contains introduction to fabrication, solutions to such threats, management of fabrication mitigation in collaborative or peer to peer location privacy and its cost analysis. There are various infrastructure components in Location Based Services such as Governance Server, Point of interest POI repository, POI service, End users, Intruders etc. Various algorithms are presented and analyzed for fabrication management, integrity, and authentication. Moreover, anti-fabrication mechanism is devised in the presence of trust. Over cost analysis is done for anti-fabrication management due to nature of various cryptographic combinations.

With the feature of convenience and low cost, remote healthcare monitoring (RHM) has been extensively used in modern disease management to improve the quality of life. Due to the privacy of health data, it is of great importance to implement RHM based on a secure and dependable network. However, the network connectivity of existing RHM systems is unreliable in disaster area because of the unforeseeable damage to the communication infrastructure. To design a secure RHM system in disaster area, this paper presents a Secure VANET-Assisted Remote Healthcare Monitoring System (SVC) by utilizing the unique "store-carry-forward" transmission mode of vehicular ad hoc network (VANET). To improve the network performance, the VANET in SVC is designed to be a two-level network consisting of two kinds of vehicles. Specially, an innovative two-level key management model by mixing certificate-based cryptography and ID-based cryptography is customized to manage the trust of vehicles. In addition, the strong privacy of the health information including context privacy is taken into account in our scheme by combining searchable public-key encryption and broadcast techniques. Finally, comprehensive security and performance analysis demonstrate the scheme is secure and efficient.

다수의 민간기업체 및 공공기관들은 영업, 홍보, 민원처리 등의 업무를 위하여 다양한 방법을 통해 개인정보를 수집하고, 조직의 이익 및 업무처리를 위해 개인정보를 활용하고 있다. 하지만 이렇게 수집된 개인정보에 대한 기술적, 관리적 조치 및 내부통제의 미숙으로 인해 개인정보의 오남용 및 유출이 사회적 문제로 크게 대두되고 있으며, 정부에서도 개인정보보호에 대한 중요성을 인식해 개인정보보호법의 시행을 추진하고 있는 실정이다. 본 연구에서는 조직에서 관리하고 있는 개인정보의 취급 패턴을 분석하여 이상징후를 탐지하고, 사전에 개인정보 유출 및 오남용에 대한 대처가 가능한 방안에 대해 기술하고 있다. 특히 개인정보 유출과 관련된 요소들을 객관적으로 측정이 가능한 핵심위험지표들로 수치화하여 관리할 수 있는 개인정보 유출 모니터링 시스템의 설계 방안에 대해 제시하고자 한다.

This study intents to provide useful information of effective office works by evaluating existing office work environment. It focuses on evaluating the quality of personal and common work spaces, comparing responses for user groups to their work environment, and identifying factors which affect the satisfaction of work environment . The study is based on the survey which has been answered by 193 respondents from 24 companies (mainly from large corporate companies) in Seoul. This study finds out that noise is the most serious problem in common work space and that environmental comfort and the size of common space are not satisfactory in their effective work. It identifies that open space work environment, which has been expansively provided for a long time, causes noise problem and deprives office workers of privacy and personalization opportunities. The respondents reply that meeting spaces are not enough in number and size and lack of privacy and its adequate quality . They respond that privacy , chair comfortness and storage spaces are important factors for personal work spaces. In order to improve the quality and efficiency of work, this study proposes that companies should provide convenient office facilities which considering human ergonomic and should educate professional facility managers.
